JMX监测ActiveMQ中队列的状态

 

ref: 

http://activemq.apache.org/jmx.html

 

1.enable JMX support useJmx="true"

<broker xmlns="http://activemq.apache.org/schema/core" brokerName="localhost" dataDirectory="${activemq.data}"  useJmx="true">
...

 

2.enable createConnector,set connectorPort and jmxDomainName  

<managementContext>
<managementContext createConnector="true" connectorPort="11099" jmxDomainName="jmx-broker"/>
</managementContext>

 

3.java code

public class TestMqStatus {
public static void main(String[] args) {
       //JMXServiceURL url = new JMXServiceURL("service:jmx:rmi:///jndi/rmi://localhost:"+RunServer.connectorPort+RunServer.connectorPath);
JMXServiceURL url;
try {
url = new JMXServiceURL("service:jmx:rmi:///jndi/rmi://localhost:11099/jmxrmi"); //jmxrmi is connectorPah
JMXConnector connector = JMXConnectorFactory.connect(url, null);
       connector.connect();
       MBeanServerConnection connection = connector.getMBeanServerConnection();
 
       // 需要注意的是，这里的jmx-broker必须和上面配置的名称相同
       //ObjectName name = new ObjectName(RunServer.jmxDomain+":BrokerName=localhost,Type=Broker");
       //ObjectName name = new ObjectName("jmx-broker:BrokerName=localhost,Type=Broker");//Windows下不区分大小写
       ObjectName name = new ObjectName("jmx-broker:BrokerName=localhost,Type=Broker");//Linux下区分大小写
       BrokerViewMBean mBean =  (BrokerViewMBean)MBeanServerInvocationHandler.newProxyInstance(connection, name, BrokerViewMBean.class, true);
       // System.out.println(mBean.getBrokerName());
       
       for(ObjectName queueName : mBean.getQueues()) {
           QueueViewMBean queueMBean =  (QueueViewMBean)MBeanServerInvocationHandler.newProxyInstance(connection, queueName, QueueViewMBean.class, true);
           System.out.println("\n------------------------------\n");
           System.out.println("States for queue --- " + queueMBean.getName());// 消息队列名称
           System.out.println("Size --- " + queueMBean.getQueueSize());// 队列中剩余的消息数
           System.out.println("Number of consumers --- " + queueMBean.getConsumerCount());// 消费者数
           System.out.println("Number of enqueue ---" + queueMBean.getEnqueueCount() );// 入队数
           System.out.println("Number of dequeue ---" + queueMBean.getDequeueCount() );// 出队数
       }
} catch (Exception e) {
e.printStackTrace();
}
       
  }
